To aZZ whom it mayA concern.-

. Be it known that l, WILLIAM Scorr, a citizen of the United States of America, and a resident of the town of Medford, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Seat-Connections for Vater-Closets, Cisterns, Tanks, dac., of which the following is a full, clear, and exact description.

As is well known, a water-closet bowl having an overhead tank or cistern and a waterconnection of tank and bowl for ushing the bowl that is controlled by a valve opened and closed by mechanism suitably applied therefor to the valve has had a seat hinged at its rear edge to a suitable support and adapted otherwise normally to be more or less but comparatively slightly elevated above the bowl, and on its depression followed by its return to its normal position, to cause an operation of the valve-operating mechanism to open and close the valve, and thus secure the ushing of the bowl with water from the cistern; and this invention, in substance, consists in a hinging of said arm at one end portion on the seat at or near its rear edge and f having its opposite end portion free, in com- Ibination with a loop which is held on a suitable stationary support and is arranged to embrace a portion of the length of the lever between its opposite ends, so as thereby to support said arm and allow it to move lengthwise therethrough and upward and downward thereon and all otherwise, as hereinafter fully appears.

In the drawings, forming part of this speciication, Figure 1 is a front elevation of a water-closet bowl, of the edge of the hinged seat, with'the seat in its normal position, and of the lower end portions of a water-passage for iiushing the bowl, and of a vertical rod for operating the valve mechanism to open and close its valve, all as well known. Fig. 2 is a central vertical section from front to rear of the water-closet bowl and its seat and a vertical section in a corresponding direction of the mechanism of this invention, as will hereinafter appear, but in a parallel plane to the known, has a width or diameter much less pear.

than that of the width of the bowl from side to side. Fig. 3 is-a vertical section, on an enlarged scale and in a direction from front to rear of the seat, of a portion of the seat and of the support to which it is hinged and a side view of the rear extended arm and loop therefor, both of this invention and in the most preferable form, as will hereinafter ap- Fig. e is a face view of the under side of the seat-arm, Fig. 3. Fig. 5 is a transverse vertical sectionvof the guide-loop for the seatarm, Figs. 3 and 4, and also of said arm in its position in the loop when the seat is depressed. Fig. 6 is a cross-section of the loop, Fig; 5.

In the drawings, A is a water-closet bowl.

B is a seat for the bowl hinged at its rear edge to the front edge of a horizontal shelf or support C, suitably fastenedto the wall of a room or otherwise supported.

D is a water-pipe, at its lower portion in connection with the flushing-rim of the vbowl and at itsupper end portion vin communication with an overhead water tank or cistern. (Not shown.)

sis

E is the lower portion of a vertical rod,

lowered, an opening and closing of the valve of said tank, and each and all and in every particular, as well known, and needing no particular description herein and foriningno part of the present invention, except, however, as they either separately or together are in combination with the features of this invention.

The normal position of the seat is slightly elevated at its front edge, and which may be secured by springs suitably applied or otherwise, all as well known, but as particularly secured by this invention, because of the Weight of the valve-operating rod E and of its attachments, if any, as will hereinafter appear.

F is an arm held on the seat and projected IOO and in its other part held on the arm-extension F, and together they are adapted, when the seat is depressed, as in Fig. 3, to be in abutment and to have the arm-extension in substantially the horizontal plane and as a rearwardextension of the seat. The arm-extension F, Fig. 8, is a flat piece of metal having a rib J on its upper side to stiffen it, and the rib J, with the arm in the extended position (shown in Fig. 3) is received in a suitable cut-away portion K at the under side of the shelf C, to which the rear edge of the seat is hinged. Again, the arm-extension F intermediate of its length and preferably on each of its opposite edges a a, Figs. 3 and 4, has a corresponding cut-out portion or recess L, both of which are directly opposite each other and for a purpose as will hereinafter appear. M is a metal loop or clasp held on and projecting downward from the underside of the support or shelf C, to which the bowlseat B is hinged. The arm-extensionF of the seat is entered into and is free to play lengthwise through the loop M. The inside width,`

Fig. 5, of the loop M at its upper portion M2 is atleast equal to butin any case not greater than the width of the arm-extension F at its narrower portion L L, and at its lower portion M3 its inside width is equal to that of the arm-extension F for its length other than that embraced by its narrower portion L L. Furthermore, the loop M, Fig. 3, is located on the seat-supportl C, and the narrow portion L L of the arm-extension is located as to the full length of said arm-extension, so that the armextension abutted against the rear hinged edge of the seat will then, by its narrow por .tion L L, be within the narrow upper portion M2 of the loop, and on a lifting of the seat will allow the arm-extension thereof to then swing on its hinge H downward and enter into the wider lower portion M3 of the loop for its then movement forward and backward therethrough, resting on the lower side thereof on a swing of the seat into a more or less vertiycal position against the wall, as shown in Fig.

A widths of the upper and lower portion of the loop in co-operation with the relative widths of the arm-extension, all as described, the loop acts to secure and insure as the seat is depressed a presentation of the outer end portion F2 of the arm-extension in proper relation to the lower end of the rod E for operating the valve of the tank by holding the armextension at all times against moving upward in the loop until such movement is required in order t-o lift the rod E and then to allow it to move upward, as desired.

The arm-exten sion of the seat is held against moving upward, as stated, because of a then travel of its wider portion through the narrow portion of the loop, during which it is, as is plain, overlapped by the narrow portion of the loop, and when the narrow portion of the arm-extension is suihciently in apposition to the narrow portion of the loop the restraint of the loop against the upward movement of the arm-extension is removed, and if then the lengthwise movement of the arm-extension in its direction of movement on a depression of the seat to the bowl is continued its said upward movement then takes place, lifting the rod, and so, on a return of the rod, as the seat returns to its normal position, and the arm-extension is thereby suitably displaced therefrom, securing, as is well known, an opening and closing of the valve of the tank, and thereby a flushing of the bowl. loop M, having upper and lower portions of comparatively different widths, and a hinged armextension at and from the rear and hinged end of the seat, and of comparatively different widths along its length and in com-l bination, all as has been described, are obviously most preferable. This comparative difference in width of the loop and of the arm-extension F relatively thereto, however, may be dispensed with and the loop and armextension be each of uniform width through` out, and yet the upward and downward movement of the arm-extension for the depression of the seat secured; but with such a loop and arm-extension there would be more or less danger of an improper presentation of the armfextension relative to the operating-rod E for the valve-mechanism, especially .if the seat, having been swung up to uncover ICO IIO

of which, as is well known, is more or less below the top of the bowl.

Having thus described my invention, what l claim, and desire to secure by Letters Patent, is-

l 1. The combination, with a waterclosetand a seat therefor hinged at its rear edge to a suitable support, of an arm-extension F of the seat at one end hinged thereon and to abut thereagainst and a guide-loop M for said arm F held on the support to which the seat is hinged, all so that said hinged armextension is moved lengthwise through said loop to operate the closet-valve by the depression of the seat, substantially as described, for the purposes specified.

2. The combination, with a water-closet and a seat therefor hinged at its rear edge to a suitable support, of an arm-extension F of the seat at one end hinged thereon and to abut thereagainst and narrowed in Width at an intermediate portion of its length and a guide-loop M for said arm F held on the support to which the seat is hinged and in its portions adjacent to and farther removed from said seat-support of widths corresponding, respectively, to the narrowed and Wider portions ofthe arm-extension, substantially 1o as described, for the purposes specified.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. Y
